FAQs
The DH361NRK is designed for a three-pole, four-wire setup with a fusible-neutral configuration. Install the NEMA 3R enclosure in a suitable location, connect #14-2 AWG Cu/Al conductors to the terminals, and ensure proper alignment of the neutral conductor. Verify voltage rating of 600 V and ensure wiring complies with local codes and the UL Listed listing. Proper torque and fuse selection per Class H are essential for safe operation and reliable protection.
Key specs include a 30 A amperage rating, 600 V voltage rating, NEMA 3R enclosure, a three-pole configuration with four wires, and a HP rating up to 20 hp for 1/3-phase at higher voltages. It uses fusible with neutral, supports #14-2 AWG Cu/Al conductors, and carries UL Listed certification for compliance and safety in industrial installations.
Yes. The DH361NRK features a NEMA 3R enclosure and painted galvanized steel construction, designed to withstand outdoor and dusty or wet environments. This makes it suitable for outdoor equipment, motor control panels adjacent to industrial facilities, and other harsh locations where dependable electrical protection and enclosure integrity are required.
The DH361NRK carries UL Listed certification, confirming compliance with recognized electrical safety standards. While CE or IP ratings are not specified in the data, the UL listing and NEMA 3R enclosure provide strong regulatory and environmental protection signals for many industrial installations, helping streamline procurement and compliance audits.
Maintenance needs are minimized by a robust enclosure and reliable fuse-based protection, reducing unexpected outages. With a 30 A rating and HP up to 20 hp, it supports efficient motor protection in common 1/3 HP to mid-size pump and conveyor applications. The UL Listed rating also aids in compliance, potentially lowering audit costs and downtime while improving overall equipment availability.
